1o @ZZ lic/rom t may conce-rn.' Be it known that I, IVALrnn A. Becarios, a citizen of the United States, and a resident of Tvlf'vilmette, in the county ofl Cook and 5 State of Illinois7 have invented certain new v`and useful Improvements in Bumpersa of which the following is a full, clear, and eX- act description.

My invention relates to bumpers for Ford a cars, particularly Ford trucks7 and the 0bject of the invention is to provide a stronger and more compact bumper,` and one which is more adapted to truck service than the type of bumpers now in use on Ford trucks. l5 The construction and the application of my improved bumper is shown on the accompanying drawing, in which--V Fig. l is a frontl elevational view of a 'Ford machine showing the bumper in place thereon,

Fig, 2 is a plan View Yof the bumper,v F ig. 3 is an enlarged sectional view on v `plane 3-3, lFig. 2, and n c F i is an enlarged sectional view on plane 4 4-, Fig. 3.

In Fig. i.. 5 represents the front cross- 'member of the chassis frame, 6 represents `the radiator. and 7 represents the lamp supporting brackets which extend from the Il" chassis near the front corners thereof.

The bumper bar 8 of my improved bumper structure is of U-shape and preferably made from a single piece of channel bar with the channel flanges extending inwardly.Y The U-shape bar is of just sufficient width to span the radiator at the lower end thereotl and to atl'ord protection for the lamp brackets and lamps. The bumper structure is supported so that all blows thereon are taken up directly by the chassis and; I provide the brackets B which may be detachably seured against the front cross member 5 and which rigidly support the bumper bar 8 in horizontal position. Each bracket comprises a base part 9 and a for wardly extending wall 10 against which the ends of the bumper bar are secured. The base 9 detlects downwardly at an .angle with reference to the vertical wall 10 s0 as to fol- 5 ears 13 being provided at the inner end of each base for the bolt ll and the ears le being provided at the outer end of the base for the bolt l2, thev bolt 1l extending around the cross member 5. In order to extend the bumper bar a -distance beyond the radiator sides so as to aord better protection for the lamp brackets and lamps, the bases 9 extend beyond the ends of the cross member and the bolts 12 receive the lamp brackets '7. The bumper bar supporting walls l0 appear outside of the radiator and the limbs' of the bumper bar engage against the outer sides of the walls as clearly shown in Fig. 3. To afford greater supporting strength` upper and lower flanges 'l5 and l5 are provi-ded on the walls 10 between which the bumper barendis are rigidly held against vertical displacement. At its ends the bumper bar engages directly against the bases 9 of the brackets7 and bolts or rivets 1,7 extending through the bar and the walls 1t) rigidly lock the bar in its supported po.- sition, all bumps on the bar being directly communicated to the brackets anda by the brackets to the machine chassis frame. As shown in Fig. 4, the bases 9 of the brackets have channels or depressions 18 in their rear sides for receiving rivetheads or other pro-r jections on the front face of the cross member 5 so that the base members may engage flatly against the cross member at all times and be securely seated thereagainst. To strengthen the brackets the websl) are provided between the bases and the walls l0, ea'li bracket being rnfeferably in the form of an integral casting. There the lamp brackets supportingbases extend a. distance in trout of the chassis frame. the bolt receiving wings 14. may be offset forwardly a distance from the bases 9, as shown in Fig. 2. Y The limbsiof the bumper bar 8 are substantially in direct alinement with the side beams of the chassis frame so that all blows will be taken up by the chassis frame and not by the vlamp brackets, the lamp brackets serving merely to assist in supporting the bumper in place, and the bolt receiving wings, being in front of the lamp brackets. will afford protection for such brackets.

The bumper struct-ure of my invention is very compact and possesses great strength` all bumps against the bar 'being transmitted directlv rearwardly to the chassis frame of the vehicle, the bar sides being in line and parallel with the chassis side beams. My

improved structure is also more resistant to side bumps than are the looped fender structures now extensively used on Ford cars. l malle the corners L? of my U-bnmper bar well rounded, this preventing interlocking or catching ot the bumper structure in eollisions and act-s to dei'leet and fend otlf other vehicles. The gradual bend also greatly increases the strength of the bumper structure. By being compact and with its rigid sides alongside et the radiator, greater protection is afforded tor the radiator, and, by extending Well lorn'ardly, it shields and protects the lamp brackets and laniips from luirnps and blows. lot only is my compact structure stronger and more etlicient than the .laterally extended l'iuisj. structure heroto'fore used, but it gives a more ellicient and satisfactory appearance to Ford cars, especially trucks.

I do vnot desire to be limited to the enact construction and arrangement shown, changes and inodiiications are possible which would still come within the scope oi' the in vention.

`l claim as my invention l. ln a bumper for ehicl-es, the combination of a Ll-shaped bumper bar, brackets secured to the ends oit said bar and having inwardly and transversely extending' portions shaped to tit againstthe front face ot the Yfront cross-member ot the vehicle chassis and perforated portions extending above and belen7 said members, and U-bolts having` their legs extending forwardly above and belen7 said member and extending across the back ot' said member to ksecure the brackets against the `ifront ot' and to said member.

2. bumper structure for vFord motor vehicles comprising" a U-shape bumper bar,

supporting brackets, each bracket having a rase part and a wall extending- 'forwardly therefrom intermediate its ends, said bumper bar engaging at its ends against said base parts and against the Outsides oit said vWalls and being,r rigidlyseeured to said Walls, the inner ends ot said base parts being adapted to engage, against the i'ront ltace of the front cross member olil the Vehicle chassis frame, Wings on said inner ends for receiving U-bolts which engage around the cross member, the outer ends ol said base parts being in iront oi" the lamp supporting bracaets ot the Vehicle and beineprovided 'with bolt. holes lor receiving fastening members adapted to engage with said lamp brackets.

The combination with the rhassis traine of a. Ford motor vehicle, o'tf a bumper strueture, said bumper structure connln'ising; :i U- shape bumper bar and supporting' brackets therefor, each bracket comprising` u base part and a Wall extending` forwari'lljy' therefrom, each Wall beingi channeled longitudinally on its outside to receive the side Walls of said bumper bar, means for securing the bumper bar to said walls, said base parts being adapted to fit against the Jfront tace o'f t-he "r'ront cross member'of the chassis and the distance between the ends ot said bumper bar being substantially equal to theI horizontal extent of said cross member whereby the side ot said bar will extend horizontally forwardly in line with the side beams of the chassis frame, the outer ends ot said base parte extendinga distance in front oit the lamp supportingT brackets on said chassis frame.

In Witness whereof, l hereunto subscribe my name this 9th day of September A.. D., 1,921.
